摘要： A first drive cam groove extends from a drive cam specific position to one side in a circumferential direction. A second drive cam groove extends from the drive cam specific position to the other side in the circumferential direction, and an inclination angle of a groove bottom with respect to one end surface of the drive cam main body is larger than that of the first drive cam groove. A first driven cam groove extends from a driven cam specific position to one side in a circumferential direction. A second driven cam groove extends from the driven cam specific position to the other side in the circumferential direction, and an inclination angle of a groove bottom with respect to one end surface of the driven cam main body is larger than that of the first driven cam groove.

摘要： A clutch assembly, the assembly may include a first member having a locking structure and a second member having a receiving area. The assembly may include a locking element supported in the receiving area of the second member, the locking element moving between an engaged position where the locking element holds or transfers torque between the first and second members and a disengaged position where the locking element holds or transfers no torque between the first and second members. The locking element includes a socket. Moreover, the assembly may include a reciprocating member in the socket when the locking element is in the disengaged position.

摘要： A clutch device includes a pressure plate movable toward or away from a clutch center and rotatable with respect to the clutch center. The pressure plate includes a flange extending radially outward from an outer circumferential edge of a body, pressure-side fitting teeth projecting in a first direction from a front surface of the flange, holding input-side rotating plates and output-side rotating plates, and circumferentially arranged, and a flange-side recessed portion recessed in the first direction from a back surface of the flange. As seen in an axial direction of an output shaft, the flange-side recessed portion at least partially overlaps one of the pressure-side fitting teeth.

摘要： A coupling and control assembly including a non-contact, linear inductive position sensor is provided. The assembly includes a coupling housing and a stator structure disposed within the coupling housing and including a stator housing. A translator structure is coupled to a coupling member of the assembly to rotate therewith about a rotational axis. The sensor is mounted on one of the housings. The translator structure includes a coupler element made of an electrically conductive material. The sensor is configured to create a magnetic field to induce eddy currents in the electrically conductive material. Movement of the coupler element changes a magnetic field caused by the eddy currents. The sensor provides a position feedback signal for vehicle transmission control. The signal is correlated with the linear position of the translator structure along the rotational axis.

摘要： A state changing unit is capable of contacting a clutch, and being configured to receive a force along the axial direction from a translation portion and change a state of the clutch to an engaged state or a disengaged state according to a position of the translation portion in an axial direction relative to a housing. A fixed end is non-rotatable relative to the housing. A return spring is disposed on a side of the fixed end opposite to the clutch, and capable of urging the translation portion in a direction away from the clutch with respect to the fixed end.

摘要： A system for using a motor to control a power transmission device for driving a vehicle is provided with a clutch member movable bidirectionally in an axial direction; a base member prevented from rotating about an axis; a counter member axially away from and opposed to the base member, the counter member being restrained from moving in both a circumferential direction and the axial direction; an action member interposed between the base member and the counter member, movable in the axial direction, drivingly coupled with the clutch member, and coupled with the motor to create a rotational motion about the axis; and a cam slope tilting in the circumferential direction and ascending from the base member toward the counter member to convert the rotational motion into a motion of the action member in the axial direction.

摘要： A method for operating a robotic joint of a robotic system comprising selectively operating a clutch mechanism of a clutched joint module in an engaged state to cause a quasi-passive elastic actuator to enter an elastic state, the clutched joint module operating about and defining a joint of the robotic system. The method comprising effecting a first rotation of the joint to cause the quasi-passive elastic actuator to store energy during at least a portion of the rotation of the joint. The method comprising effecting a second rotation of the joint and causing the stored energy from the quasi-passive elastic actuator to be released in the form of an augmented torque applied to an output member of the clutched joint module. The method comprising selectively operating the clutch mechanism in a disengaged state to cause the quasi-passive elastic actuator to enter an inelastic state. The method comprising effecting a third rotation of the joint, wherein the quasi-passive elastic actuator facilitates a free swing mode of the clutched joint module and the joint.

摘要： A hub unit for a clutch of a vehicle with a handlebar has both a servo function when closing and a slipper function via the sliding motion of at least one pin along respective inclined and facing tracks. The hub unit includes a hub connected to an output shaft of a vehicle engine and having an axis of rotation, a plurality of guides rigidly connected to the hub, an axial stop rigidly connected to the hub, a disc pressure flange movable in a direction parallel to the guides, and at least one spring. The hub defines at least a first track and a second track facing in an axial direction and arranged in a direction not parallel to the axis of rotation. The disc pressure flange includes at least one pin projecting in a substantially radial direction and arranged in contact with the first track and the second track.
